Packging Machine Provided With Variable-Inclination Work and Load Surface

Abstract

The present invention relates to a packaging machine provided with variable-inclination work and load surface ( 7 ), designed in such a way that the same packaging machine can be used to pack both stable products by means of lateral pushing means ( 3 ) and loose products by means of loading devices ( 10 ) from above.

1 . Packaging machine provided with variable-inclination work and load surface, of the type comprising:
 a—a storage compartment ( 4 ) of the boxes ( 1 ), where the boxes are open on both bottom edges and have a two-dimensional flattened configuration;   b—an operative unit ( 5 ) designed to pick a box at a time from the storage compartment ( 4 ), open the box and give it a parallelepiped volume, while conveying the box towards the means used to transport the boxes ( 1 );   c—transportation means ( 6 ) of the boxes ( 1 ) along a forward direction (F 1 );   d—transport means ( 2 ) of the products (P) along a forward direction (F 2 ) parallel and side by side with the aforementioned forward direction (F 1 );   e—pushing means ( 3 ) designed to introduce the products (P) into the mouth ( 1   a ) of each box ( 1 ) according to a transfer direction orthogonal to the forward direction (F 2 ) of the transport means ( 2 );   f—closing means of the edges and tongues that form the bottoms ( 1   b ) of each box ( 1 );   g—motor units with relevant driving units (T);   h—a cabinet (A) used to contain the electrical components and PLC;   i—a bearing base ( 8 );   l—a bearing panel ( 7 ) that protrudes from the base ( 8 ) and supports, in protruding position, either directly or indirectly, at least the said storage ( 4 ), operative unit ( 5 ), transport means ( 6 ), closing means of the edges ( 1   b ), motor units and relevant driving units (T);   machine characterized in that the bearing panel ( 7 ) is hinged to the base ( 8 ), in such a way that it oscillates by means of actuators ( 9 ) around a horizontal axis (X-X) parallel to forward direction (F 1 ) of the said transport means ( 6 ).   
   
   
       2 . Machine as claimed in  claim 1 , characterized in that the panel ( 7 ) also supports the transport means ( 2 ) in projecting position. 
   
   
       3 . Machine as claimed in  claim 1 , characterized in that it comprises means ( 10 ) to load the product from above, consisting in one or more hoppers, whose unloading mouth ( 10   a ) is aligned with the mouth of the box ( 1 ) below when the panel ( 7 ) is tilted backwards. 
   
   
       4 . Machine as claimed in  claim 3 , characterized in that it comprises servomechanisms of known type designed to automatically adjust the position of the said loading means ( 10 ) according to the inclination angle given to the panel ( 7 ), in such a way that the unloading mouth ( 10   a ) is positioned above the mouth of the box ( 1 ) below. 
   
   
       5 . Machine as claimed in  claim 1 , characterized in that the transport means ( 2 ) of the products (P) are positioned and fitted onto the base ( 8 ).
